TECHNICAL FIELD

The present disclosure relates to compounds that are somatostatinreceptor type 4 agonists.

BACKGROUND

Somatostatin, also known as somatostatin release inhibitory factor(SRIF) is a cyclic peptide distributed throughout the human body, and isinvolved in numerous physiological processes. SRIF occurs as atetradecapeptide and an N-terminally extended form (SST-28).

There are six somatostatin receptor (SSTR) subtypes; SSTR 1-5, includingthe alternatively spliced SSTR2A and SSTR2B receptors. The somatostatinreceptors were originally divided into two families based on bindingstudies with iodinated synthetic analogues of somatostatin; a highaffinity family (SRIF-1) and a lower affinity family (SRIF-2). When SRIFbinds to its receptors, it produces changes in intracellular signalingpathways. SSTRs are all G-protein coupled receptors (GPCRs). Throughreceptor action, SRIF produces primarily inhibitory effects on endocrineand exocrine secretions throughout the body, regulates cellulardifferentiation and proliferation, and acts as aneurotransmitter/neuromodulator in the central nervous system. GivenSRIF has shown to exhibit inhibitory actions on endocrine and exocrinesecretions, as well as numerous modulatory effects on neuronal activityin the periphery and central nervous system (CNS), the respectivereceptors have become primary therapeutic targets.

Binding assays were performed using1251-Tyr-SRIF 14 (Perkin-Elmer, NEX 3890) dissolved in 1 mM HCl. Bindingassays were performed in triplicate for each concentration of ligand ina total volume of 200 μL radioligand (25 μL ligand, 25 μL radioligand,150 μL receptors) and incubated at room temperature for 90 minutes usinga shaking table. Binding was terminated by filtration through GF/B glassfiber filters that were presoaked in 0.5% polyethyleneimine for aminimum of 4 hours. Filters were washed 9× with 1000 μL ice cold washbuffer (50 mM Tris-HCl, pH=7.4, 0.2% BSA). Filters were scored,transferred into plastic test tubes and counted in a gamma counter(Wizard2, Perkin-Elmer). Determination of the Ki for each compound wasperformed using non-linear regression with GraphPad PRISM-5 software(GraphPad Software, Inc., La Jolla, Calif.).

Example 4: Activity Assays

Measurement of forskolin stimulated inhibition of cAMP was performed viatime-resolved fluorescence resonance energy transfer (TR-FRET) LANCEassay (AD0262, PerkinElmer Life Science, Inc., Boston Mass.).Recombinant Chinese hamster ovary (CHO-K1) cells expressing humansomatostatin SSTR4 cells (ES-524-CF, PerkinElmer Life Science, Inc.,Boston Mass.) were thawed (37° C.), resuspended in 10 mL Hanks' balancedsalt solution no phenol red (HBSS, Invitrogen, Carlsbad Calif.), andthen centrifuged (150×g, 5 minutes). Cellular pellet resuspended instimulation buffer containing HBSS 1×, HEPES 5 mM, Protease free BSA0.1% (PerkinElmer), and 3-Isobutyl-1-methylxanthine 0.5 mM (pH 7.4) andseeded in 96-well plates at 4000 cells/well. LANCE cAMP assay wasperformed per manufacture instruction with assessment of respectivecompound, somatostatin-28 (Sigma-Aldrich Co., St. Louis, Mo.) as controlagonist, against 5 μM forskolin, performed in triplicate acrossconcentration curve. Fluorescence signal was measured at 20 hours(excitation 340 nm and emission 665 nm, 400-μs delay) via TR-FRET(FLUOSTAR Omega-F, BMG Labtech, Inc., Cary, N.C.). Data was calculatedvia GraphPad PRISM-5 software.

Measurement of β-arrestin was conducted with use of the PATHHUNTEReXpress SSTR4 CHO-K1 β-Arrestin GPCR Assay (93-0308E2, Discover Rx).PathHunter EXPRESS β-Arrestin SSTR4 cells (CHO-K1, DiscoverX) areengineered to co-express the PROLINK (PK) and the Enzyme Acceptor (EA)tagged β-Arrestin. Activation of the SSTR4-PK induces β-Arrestin-EArecruitment, forcing complementation of the two β-galactosidase enzymefragments (EA and PK). Cells were thawed and diluted in cell-platingreagent, with subsequent plating in 96-well plate (100 μL/well) andincubated at 37° C./5% CO₂ for 48 hours. Serial dilutions of controlcurve (somatostatin-28, Sigma-Aldrich Co., St. Louis, Mo.) andcompound(s) being tested are added after 48 hours incubation. Aftersubsequent incubation with control/compounds for 90 minutes, detectionreagent is added followed by a 1 hour incubation. The resultingfunctional enzyme hydrolyzes substrate to generate a chemiluminescentsignal which is measured (FLUOSTAR Omega-F, BMG Labtech, Inc., Cary,N.C.). Data was calculated via GraphPad PRISM-5 software.
